I have known Kurt Rosenast for over 10 years as a friendly and fair real estate agent. He sold our corner property for us, even though interest rates were already rising. Kurt also organized and coordinated the bank and notary matters for us. I can only recommend rosenast finance & real estate solutions. W. and I. Herrmann, Bilten

We commissioned Mr. Imfeld with the sale of our condominium. The valuation and the creation of the listing were already very professional and implemented quickly. Even though the sale turned out to be somewhat more difficult than expected, he was always very committed, going beyond the usual clarifications. Thank you very much for the successful sale.

From the very first second until the end - and beyond - we experienced Stefan as friendly, knowledgeable, and always professional. The property was systematically and thoroughly evaluated. Two other independent assessments came in at the same price. It was good to know that we were not selling below value, but also that we were not trying to deceive anyone with an inflated price. The entire process was expertly managed and went smoothly. Communication was always timely and purposeful. The experience: simply first class!

I would like to sincerely thank Alexander Riesch and his Bündner real estate team for the excellent service throughout the entire sales process of my penthouse apartment in Niederhasli. I was very impressed by their professional and friendly manner. I can highly recommend Mr. Riesch and his team. If I had another property to sell, I would definitely grant the mandate again to Bündner Makler. Thank you very much and continued success and all the best Marcel K.

I had a very good experience with Cosmos Values AG and the agile and goal-oriented Ms. Rena Wisler. Everything was very professional and perfect, which led to a good, fair sales result / sale price. The support for the buyers was also exemplary and of high quality. The entire formal sales process from the notarial purchase contract to the transfer of ownership was perfectly and stress-free organized. By the way: I found Ms. Wisler through a recommendation from enthusiastic acquaintances who previously used the services of Cosmos Values for the sale of real estate.
